X-rays with a wavelength of 8.82 nm. Calculate the frequency of the x rays

Chemistry
1 answer:
krok68 [10]3 years ago
6 0

Answer:

The wave with the wavelength of 8.82 nm have frequency of 0.340 × 10¹⁷ s⁻¹.

Explanation:

Given data:

Wavelength of x-ray = 8.82 nm

frequency of x-ray = ?

Solution:

speed = Wavelength × frequency

frequency = speed /  Wavelength

c = 3 × 10⁸ m/s

f = c/ λ

f = 3 × 10⁸ m/s /8.82 × 10⁻⁹m

f = 0.340 × 10¹⁷ s⁻¹

The wave with the wavelength of 8.82 nm have frequency of 0.340 × 10¹⁷ s⁻¹.

_____ bonds are formed when the electronegativity difference is 0.4 > 2.0. Give two examples:
34kurt

<u>Ionic Bond</u> is formed when the electronegativity difference is 0.4 > 2.0. Electronegativity is a term that can be defined as a tendency of an atom to attract electron towards its own self.

Explanation:

Electronegativity is a term that can be defined as a tendency of an atom to attract electron towards its own self.

An  electronegativity of an atom is affected by

  • The atomic number of the atom
  • Secondly by the distance at which the valence electron are residing from the nucleus

1. In case the  electronegativity difference (which is denoted by  ΔEN) is less than 0.5  then the bond formed is known as N<u>onpolar covalent. </u>

2. In case  the ΔEN is in between 0.5 and 1.6, the bond formed is referred to as the<u> Polar covalent </u>

3. In case  the ΔEN is more /greater  than 2.0, then the bond formed is referred to as<u> Ionic Bond</u>

<u>2 Examples of Ionic bonds</u>

  • The formation of sodium fluoride, NaF, from a sodium atom and a fluorine atom is an example of Ionic bond formation.
  • Another example is the formation of NaCl from  sodium (Na),which is  a metal, and chloride (Cl), which is a  nonmetal

When silver nitrate reacts with copper, copper(II) nitrate and silver are produced. The balanced equation for this reaction is:
posledela

The question is incomplete, here is the complete question:

When silver nitrate reacts with copper, copper(II) nitrate and silver are produced. The balanced equation for this reaction is:

2AgNO_3+Cu\rightarrow Cu(NO_3)_2+2Ag

Suppose 6 moles of silver nitrate react. The reaction consumes___ moles of copper. The reaction produces __ moles of copper(II) nitrate and __ moles of silver.

<u>Answer:</u> The amount of copper metal reacted is 3 moles, amount of copper (II) nitrate produced is 3 moles and amount of silver metal produced is 6 moles.

<u>Explanation:</u>

We are given:

Moles of silver nitrate = 6 moles

For the given chemical reaction:

2AgNO_3+Cu\rightarrow Cu(NO_3)_2+2Ag

  • <u>For copper metal:</u>

By Stoichiometry of the reaction:

2 moles of silver nitrate reacts with 1 mole of copper metal

So, 6 moles of silver nitrate will react with = \frac{1}{2}\times 6=3mol of copper metal

Moles of copper reacted = 3 moles

  • <u>For copper(II) nitrate:</u>

By Stoichiometry of the reaction:

2 moles of silver nitrate produces 1 mole of copper(II) nitrate

So, 6 moles of silver nitrate will produce = \frac{1}{2}\times 6=3mol of copper(II) nitrate

Moles of copper(II) nitrate produced = 3 moles

  • <u>For silver metal:</u>

By Stoichiometry of the reaction:

2 moles of silver nitrate produces 2 moles of silver metal

So, 6 moles of silver nitrate will produce = \frac{2}{2}\times 6=6mol of silver metal

Moles of silver metal produced = 3 moles

Hence, the amount of copper metal reacted is 3 moles, amount of copper (II) nitrate produced is 3 moles and amount of silver metal produced is 6 moles.

Look up and record the boiling point of acetic acid, and explain why only some of it evaporates from the reaction mixture.
REY [17]

Answer:

Heating the mixture to a temperature above the boiling point of acetic acid, but below 100°C (the boiling point of water). The vapours from the acetic acid rise, and go into a tube. They are then condensed within the tube, and run off into a separate storage area. Because water can exist as a gas at pretty much any temperature above 0°C, it will result in an impure mixture, but repeatedly doing this will get the acetic acid to the desired purity.
